Japan and the European Union agreed Friday to work together to persuade the United States to overhaul antidumping rules at a new global trade round under the World Trade Organization, trade sources said. With the U.S. opposed to discussing the matter at the new round proving to be a sticking point, Japan and the EU have agreed to propose a review of the current WTO antidumping rules.

European Trade Commissioner Pascal Lamy will ask U.S. Trade Representative Charlene Barshefsky to accept the proposal in a meeting of top leaders and ministers of the U.S. and the EU in Portugal on Wednesday.
